Erin Andrews, even with the help of rapper 50 Cent, couldn't find Danica Patrick in Fox's Daytona 500 prerace show Sunday.

Andrews' assignment was to "take a fun walk in the pits and see what people are talking about," Fox Sports co-president Eric Shanks told USA TODAY Sports last week. Using that casual approach obviously brings risks compared to the usual practice of being side-by-side with interview subjects before going on-air.

Andrews, in the prerace show, said, "One cool thing about the Daytona 500 as we've been hanging out here is that there are so many celebrities."

Like 50 Cent, who showed up on-air with Andrews, announcing he was having fun, then joining Andrews in a hunt for Patrick.
